of course that is possible on apple with support of software companies. On amiga most software is no longer supported so noone would new compile it. Only solution sandboxes like using integrated UAE. Similar could be done with PPC. But it would certainly require a lot of work to do it in a way user would like it.
100% You either want Amiga in name only on x86 or be happy with 68k, PPC and emulation with updates and new apps being added to the historical library.
